Throughout sensory systems, neurons are organized by response preference, so that like-responding neurons are close to each other, creating a functional map [e.g., orientation pinwheels in primary visual cortex (V1)]. Despite the ubiquity of maps, their role is unclear. For example, although rodent ...
